Limit on ν e → ν τ Oscillations from the NOMAD experiment NOMAD Collaboration

In the context of a two-flavour approximation we reinterpret the published NOMAD limit on νμ → ντ oscillations in terms of νe → ντ oscillations. At 90% C.L. we obtain sin 2θeτ < 5.2× 10 −2 for large ∆m, while for sin 2θeτ = 1 the confidence region includes ∆m < 11 eV/c.
